“Smoke and different gases, such as carbon monoxide that can be produced in fire situations, also affect the density of the air and will give distinctive signatures on our readings. The research team from UNSW Sydney are able to monitor Wi-Fi radio signals as they pass through the air and have identified distinctive patterns in the data which are caused during fire events. Wi-Fi signal readings from fire safety test in Sydney Harbour Tunnel In fact, we have experimentally demonstrated that these changes are strongly correlated with the rise or fall of temperature in the environment between transmitter and receiver. “As the air temperature changes, so does its density, and that changes the signature of the reading when we receive the signal. What we have are a transmitter and a receiver and we can monitor the radio signal as it travels through the air,” Prof. “It is basically relatively simple high school physics. Innovation Connections is part of the Australian Government Entrepreneurs’ Programme, delivered nationally by CSIRO, Australia’s national science agency. The project to test the first real-life application of this technology was supported through Innovation Connections, which provided matched funding support to Trantek and connected researchers at UNSW with the business. Dr aruna seneviratne series#In conjunction with Trantek MST, the incumbent mission-critical systems vendor for the tunnel, and the tunnel owner/operator, Sydney Harbour Tunnel Company, the researchers set up a series of transmitters and receivers to monitor the environment as a test car prepared for the purpose was detonated and set on fire during a scheduled emergency response training exercise. Seneviratne and his team were able to showcase their new technology during a controlled test in the middle of the night inside the Sydney Harbour Tunnel. The system can then determine with greater accuracy whether any atmospheric changes are being caused by a real fire, and if so, raise an alarm or trigger an automatic sprinkler system.Įxisting detection systems, which are largely based on thermal imaging, often produce false positive readings by detecting levels of smoke or changes in temperature which are not dangerous or caused by an actual fire – perhaps from a faulty exhaust pipe on a vehicle or a hot radiator.īut Prof. Dr aruna seneviratne software#The researchers have identified the distinctive patterns in the data from radio signals during fire events, and artificial intelligence within their software helps analyse the environment in real-time. Professor Aruna Seneviratne, Dr Deepak Mishra, and a team from the School of Electrical Engineering and Telecommunications have designed and built a system that monitors Wi-Fi signals as they pass through the air – and analyses detailed changes in the environment due to such things as temperature and smoke. Engineers from UNSW Sydney have developed a new fire detection system that could help save lives by monitoring the changes in Wi-Fi signals.Īnd a controlled test detonation of a car, planned by the Sydney Harbour Tunnel Company, recently provided further data to demonstrate the effectiveness of the technology.
